This invention relates to such cigar machines in which bunches or finished cigars are produced by means of a number of rollers which when manufacturing said product surround it, and rotate all in the same direction pressing against the bunch or cigar. If cigars or bunches are treated which are tapered at their ends, the rollers cannot have a cylindrical form, and if the cigar is spool-shaped, each roller must consist of at least two parts which are movably joined, and consist each of a main roller and one or two companion rollers, the latter connected to the ends of said main roller in the manner above mentioned. In order to avoid any relative movement between the rollers and the product which is treated, the companion roller is tapered, its butt end being connected to the main roller and its top end being journaled near the centre of the bunch which is treated.

In such devices of hitherto known types there is an inconvenience consisting in that it is not possible to obtain a smooth connection at the form side of the rollers, which fact results therein that small particles of tobacco enter the joint and that the wrappers and the like, which are introduced into the rolling device, are pinched at the connection and thereby scratched.

The device according to this invention has for its object to remove said inconveniences. This is obtained thereby that a tight connection is provided at the whole or part of the connection between main rollers and companion rollers.

In the accompanying drawing there is shown a preferred embodiment of the invention.

Fig. 1 shows a longitudinal section of a devlce according to the lnvention.

and end view a detail of a roller.

Fig. 7 shows in longitudinal section a modified form of the device according to the inventlon.

A set of four main rollers 1 is arranged in a frame divided in upper part 2 and lower part 3 hinged at 4. Rods 5 are firmly inserted 'into the frame parts, their free endsbeing provided with bushings 6, on which the main rollers 1 are journaled. At the-open end of the rollers small pinions 7 are firmly .connected. Said pinions'are rotatably j ournaled on the rods 5 and intermesh with a gear wheel 8 fixed on a shaft 9, driven by any convenient power source. The bunch 10 is surrounded by the form rollers 1 when it is treated, and h the two upper rollers are arranged to be lifted from the two other rollers by openingthe frame part 2 in a way and with means, which form no part of the invention. The free ends of the main rollers 1 are provided with hemispherical sockets 11, in which fit hemispherical butt ends of tapered companion rollers 12, so that the connection at v the outer sharp edge 13 of the-socketll is so tight and smooth. At the bottom of the socket 11 is provided a cavity 14:, and a pin 15 is drawn across said cavity. Another cavity 16 is provided in the butt end of the companionroller, and a pin 17 provided with a 25' head 18 penetrates said companion roller, lengthwise, and projects out of the top end of the latter. A pin 19 is drawn through the head 18 and another pin 20 is drawn through the roller 12 and the pin 17, the pin 20 therego by fixing the two members last mentioned in relation to each other. An helical 'spring21 is attached at one end to thepin 15 and at its other end to the pin 19, thereby drawing the rollers together. The stress of said spring 2 may be adjusted by adjusting the'pin 17 in' different positions, and then secure it by means of the pin 20. The projecting ends of r the pin 17 are journaled in movable bearings 22. j p I By the arrangement above described is attained that the inner spaces at the sockets 11 are practically air-tight separated from the space surrounding the rollers. Except a smooth surface another advantage is ob- 9 tain-ed, it being possible to use a lubricating oil for the surfaces at the connection, which movably engage each other, without any oil leakage, and moreover no tearing particles can enter between the relative movable sur- V faces of the connection. In some cases it is thereof being secured in a socket and its other however sufiicient if a tight and smooth conend being secured to a corresponding butt nection is attained only on the working surend.

face of the rollers and the connection can be open at the opposite side. v

According to Fig. 3 the spring 21 is replaced; by another flexible member namely by a rubber pin 23, which draws the rollers together, and thus also efi'ects a tight connection. "The rubber pin is at each end provid' ed with treaded metal rings 24:, which are screwed into the bottoms of the cavities 14 and 16. i

Accordingto Fig l the spring 21 is replaced by another spring 25 acting upon the companion roller 12 in such a way that the rollers 1 and '12 are pressed together. A projection 26 from the roller 12 is journaled in a'bushing 27, whichis carried by the spring 25, which latter is inserted in a cavity-28 in the frame. The cavity 16 has in this case an oval cross section, and in the bottom of the socket 11 is inserted a pin 29 with a disc 30 which according to Fig. 6 has an oval shape reciprocating the shape of the cavity'16. v

The inventive idea is of course applicable also if cigars are produced which are tapered at both ends; In such case a device according to Fig. 7 is used. The left part of the rollers is substantially arefiected image of itsright side which latter is substantially of the same shape as the right part of the rollers shown in Fig.1. The rollers are in such case connected i. e. to flexible driving shafts 31 each driven from any suitable power source by means i. e. pinions 32 fixed to the shafts 311 and intermeshing with a central pin-i on. 33 fixed on a central shaft 3 1 coupled to the power source. In order to fix the bearings 22 in relation to the frame screws 35 are provided,-and thus the device can be used for producing bunches or cigars of any diameter.

I donot wish to be limited as to details of construction, as these may be modified in many particular parts without departing from thespirit of my invention. I 1 What I claim and desire to secure by Letters Patent of the United States of America is: Y r
